【摘要】：精锻机又称“径锻机”,是世界上最先进的锻造设备之一。精锻机具有脉冲锻打和多向锻打的特点,而且脉冲锻打频率高、速度快、每次变形量很小,省去了锻造后的打磨等工序,可实现从坯料到成品的直接加工。精锻机具有诸多优点,如锻件品质高、生产率高、材料消耗低、工艺装备少而简单、通用性强、制造周期短、自动化程度高,劳动条件好等。因此精锻机在军工、航空航天、铁路车轴、合金钢锻造及难锻造的有色金属等行业应用广泛。本文针对兰石重工有限公司制造的1.6MN精锻机进行研究,以提升企业的装备制造水平和市场竞争力,同时也填补我国精锻机领域的空白。根据精锻机的工作特点,本文重点研究了精锻机主要参数的设计计算,结构参数对主机运动参数的影响因素等问题,探索精锻机稳定工作时的参数确定方法。对精锻机的主要部件齿轮箱和锻造箱进行分析,得到合理的结构设计参数。本文在充分论证精锻机多种结构型式后,根据企业的要求及各类精锻机的特点,确定了1.6MN精锻机采用无芯轴卧式的模式,主传动采用机械传动。其主传动采用双偏心结构设计。对1.6MN精锻机进行以下了分析研究：1.对精锻机的主要设计参数锻造变形力、锤头运动参数、变形功进行分析计算,为后续的精锻机选型、设计提供理论依据。2.对1.6MN精锻机主机锤头位置控制及锻造力反馈的计算,该计算为精锻机控制部分的核心计算,同时锻造力反馈推导计算为保护主机提供数据依据。3.根据1.6MN精锻机主机齿轮箱中各齿轮的参数及驱动电机参数,并对齿轮箱中关键零件——齿轮进行齿面接触强度和齿轮的弯曲强度计算,结果证明该设计能够满足设备的工作要求。5.使用有限元分析软件Ansys Workbench对精锻机关键受力件——锻造箱体进行有限元强度分析、模态分析、动力学分析及疲劳寿命分析,仿真结果显示,锻造箱在结构强度和刚度、动载荷作用和疲劳寿命上均满足要求,模态分析也表明外载荷不会激发结构引起共振。因此,锻造箱结构在设计载荷作用下满足强度条件、刚度条件和永久设计等。设备的研制成功表明,该1.6MN精锻机具有可靠性、先进性等优点。1.6MN精锻机研制成功后,将大大的为国内企业节省大量外汇,并为后续开发系列化精锻机打下坚实的基础。
[Abstract]:Precision forging machine is also called the "radial forging machine", is one of the world's most advanced forging equipment. Precision forging machine with pulse forging and multidirectional forging and forging pulse characteristics, high frequency, high speed, each deformation is very small, omitted after forging grinding process can be realized directly from blank to processing finished. Precision forging machine has many advantages, such as high quality forgings, high productivity, low material consumption, simple equipment, strong versatility, short manufacturing cycle, high degree of automation, good working conditions and so on. So the precision forging machine in the military, aerospace, railway axles, non-ferrous alloy steel forging and to forging a wide range of applications.
